Hi Jeff. I use ordinary tuning fork qc.

I read somewhere here in this forum taht somone had a problem in bright sun light with new tuning fork qc. (module shot down or something) but I don't have this probelm with my modules.

egomon: probably because you don't have any sun in Finland right now. . actually, jeff and i have discussed this phenomena and not come to a real concete conclusion as to what exactly is the problem. it is obviously something not right in the charging system because as a rule it is not a problem. this is more than likely why these particular watches were returned to riehl to begin with. i have a few that have this problem, but for the time being just set them aside. they work fine if they don't get an excessive charge. i think jeff said that the qc shuts down because the voltage is too high. [at least i think that is what he said.] i have tried changing the qc's, but it doesn't seem to help. maybe it has something to do with the 2 resistors in the charging circuit. what do you think jeff? i was going to call you on that but never got around to it. maybe now is the time to address that. peter

My mkIII


PS - PLEASE what is the default crystal setting? I changed min by accident, and forgot. I don't feel like waiting for it to fail AGAIN to have the setting restored to the default

Best Regards,

dennis, not sure what you mean by default setting. if you are referring to the speed setting the 2 mkIV"s i have are between 600&700. from there it is trial and error altho' i think each number increment is 8'secs/yr + or -. i think there is a copy of the instr on the photo gallery. peter

Yes I am referring to the speed. It is something like 1314, when the watch powers up, but now I have been adjusting it for the last 6 months or so, because it is running too fast.

The reason I ask, it that it was SPOT ON with the default.

Oh and sorry but it is a mk III

[clockace]

i think the settings for the MkIII/IV are probably the same. what # are you showing now? 1314 sounds mighty fast to me. change it down to 700 and see what happens. peter

[dbmurphy]

Done - :) let's see how we go from there

[clockace]

db, how is the speed on your synchronar? did the lower # slow it down? peter

[dbmurphy]

Yes !!!

I changed the value down to 1320 and it is still gaining about 10 seconds a week, but MUCH better, and I am zero-ing in thanks !!!!

[clockace]

Dennis, it just dawned on me, but i think you are pushing the left slider back to see your speed reading?? the display you see is 1320? if so the 1 is the leap year setting and the speed reading is 320. i have a mkIII booklet and that is what the left back slider shows. in reality you are in the wrong year of the leap yr setting. it should be showing a 3 since we are in the 3rd year of the cycle. you should be showing a 3320. peter

OMG you are right !!!

I feel kinda' dumb now LOL but THANKS very much.

Thanks Peter,
Dennis
